MARTIN CARROLL, OF BRIGHTON PARK, ILLINOIS.

PORTABLE BRICK-DRIER.

SPECIFICATION forming part of Letters Patent No. 368,454, dated August16, 1887.

Application filed March 19, 1887. Serial No. 231,553.

To aZZ whom, it may concern.-

Be it known that I, ll'IARTIN CARROLL, of

Brighton Park, in the county of Cook and,

State of Illinois, have invented certain new and useful Improvements inPortable Brick- Driers, of which the following is a specification.

My invention relates to a novel car for use in drying bricks; and itconsists in various features and details, hereinafter fully set forthand claimed.

In the drawings, Figure 1 is a longitudinal central sectional view of myimproved car; Fig. 2, a bottom plan View of a portion of the car, Fig.3, a vertical transverse sectional view, and Fig. 4 a bottom plan viewof one of the supporting-trays.

A indicates the car as a whole, carried by wheels B B and adapted to runupon a track. This car may be built of iron or of wood, as may be foundexpedient, and it is obvious that the shape or form of the car may bevaried as desired, except as hereinafter described.

\Vithin the car I place one or more upright serewstems, O, which will besecured at their lower ends to the floor of the car and project at theirupper ends out through the roof, as shown in Figs. 1 and 3. These stemsO are adapted to receive a series of circular plates or trays, D, eachbearing a central internallythreaded .hub, a, as shown in Figs. 1, 3,and 4-, the plates or trays screwing up or down upon the screw-stem,according to the direction in which they are turned.

The stems G, with the brick-supportin g trays,

are situated directly opposite the doors of the ear to facilitate thefilling of the trays with the green bricks. Before filling the traysthey are first screwed down to their lowest positions, and as soon asone tray is filled it is screwed upward until it approaches close to theroof of the ear, and then the next tray is filled. This second tray isthen screwed up close to the bottom of the first tray, this operationbeing kept up until the trays are all filled.

The trays D will preferably be made of eastiron,with radialstrengthening-ribs on the under face, as shown in Figs. 1, 3, and 4; Ido not restrict myself to any particular construction of the trays, forit is obvious that they may be made of other materials than metal, andneed not necessarily be circular. It may be (No model.)

found desirablein some instances to perforate or make the trays orplates open, as shown in Fig. 4, in order that the heat may pass upwardthrough and between the bricks.

Extending lengthwise of the car, centrally along the under side of thebottom, is a castmetal flue, E, communicating at its ends with furnacesF, provided in its upper face with openings b, and in its lower facewith similar openings, 0, as shown in Figs. 1, 2, and 3. The flue E isfurther provided with chimneys G, which, for convenience, may be made bymaking the screw-stems O hollow, as shown in Figs. 1 and 3; but in lieuof using these stems for the purpose of carrying off the smoke, &c., aseparate chimney, situated at any desirable point, may be employed.

The furnaces may be constructed to burn either hard or soft coal, or anyother suitable fuel, and as their construction per 80 forms no part ofmy present invention, they need not be further described herein. Y

The openings 11 and c are controlled by means of rods H and I, bearingdisks (1 and e, as shown in Figs. 1, 2, and 3, those on rod H beingarranged to cover the openings b and those on rod I to cover openings 0.

From the foregoing construction it will be seen that if after fire isstarted in the furnaces the valves or disks (1 be opened the smoke andheat will pass through the openings 1) into the interior of the car andcome in contact with the bricks upon the trays and dry them, and that ifthe valves 6 also be opened the air passing through the opening 0 intothe flue E will become heated and be discharged into the interior of thecar, together with the smoke and heat from the furnaces.

In order to provide for the escape of smoke, &c., from the car thechimney G will be perforated at its upper end, as at f, Figs. 1 and 3,and to provide for the escape of steam given off by the bricks in beingdried I provide the roof of the car with ventilators J, as shown inFigs. 1 and 3.

The bottom of the car will be made of metal and have the flue E securedthereto by bolts passing through arms 9 g, projecting laterally throughfrom the flue, as shown in Figs. 2 and 3.

The car A is shown in the drawings as having a wooden framing lined withmetal; but,

null

as before stated, the entire car may be made'of metal when deemeddesirable.

It is obvious that various features of the invention are capable ofseparate and independent use, and while the car constructed and arrangedcomplete, as shown, will generally be used, I do not limit myself to acar embodying all the various. details and features enumerated.

From the foregoing it will be seen that I avoid all unnecessary handlingof the bricks, as they may be taken direct from the machine, placed uponthe trays in the car, and the latter moved away and fired up, and thebricks dried preparatory to placing them in the kiln, with but onehandling.

While I am aware that ithas been proposed to dry bricks by placing themupon cars and moving the'cars through a heated kiln, I amv not awarethat any one prior to my invention has provided a car with aheat-distributing flue. By this latter construction the heat iscompelled to pass up between and around the bricks upon the trays andall the heat utilized. The heat may obviouslybe supplied to the flue Eby means of a stationary or fixed furnace, in lieu of placing thefurnaces upon each car, and as I believe myself to be the first to soconstruct a car, I do not wish to limit myself to any particularconstruction or location of the furnace.

I am also aware thataportableasphalt-mixing machine provided with afurnace hasbeen patented, and to such construction I lay no claim; but

.What I do claim is 1. A car provided with an upright screwstem and aseries of brick supporting trays mounted thereon, substantially as shownand described.

. 2. A car provided with aseries of bricksupporting trays and with afurnace adapted to discharge heat into the interior of the car.

3. In combination with a car-provided with a series of brick -supportingtrays mounted therein, a flue extending along the floor of the caradapted to discharge heat into the latter, and a furnace communicatingwith said flue.

4. In combination with a car provided with a series of brick-trays, aflue extending along the floor of the car provided with openings on itsupper face, and a furnace carried by the car and connected with saidflue.

5. In combination with a car provided with a series of trays, a furnace,and a heat-flue pro vided with openings in its upper and lower faces.

6. In combination with a car and trays D, aflue, E, andafurnace, F, andachimney, G, all mounted upon the car, substantially asshown.

7. In combination with a car and trays D, a flue, E, and furnace F, andchimney Gr, provided with an opening, f, as and for the purpose setforth.

8. In combination with a car and trays D, aflue, E, and furnace F,ahollow screw-shaft,0, for supporting the trays and communicating withthe flue E,as and for the purpose set forth.

9. In combination with a car and trays D, a flue, E, and furnace F, andventilators J, all mounted upon the car, substantially as and for thepurpose described.

10. In combination with acar provided with a series of trays, D, afurnace, F, and a flue, E, connected with the furnace and provided withvalved openings b and c.

11. In combination with a car, an upright screw-stem, O, a series oftrays, D, mounted thereon, and a heater connected with the car andadapted to dischargeheat into the latter, substantially as described andshown.

12. In combination with a car and upright hollow screw-stems O G, traysI), mounted thereon, flue E, provided with valved openings b c, andfurnaces F F, arranged substantially as shown.

In witness whereof I hereunto set-my hand in the presence of twowitnesses.
